This invention relates to a new and useiul improvement in paper feed controlling mechanism incr calculating machines, and is an application filed by me May 20, 1910, Serial Number 98,853.

The calculating machine disclosed in the parent case is of the combined adding and typeWrit-ing machine class commercially known as the Moon-Hopkins billing ma chine, the particular type of Moon-Hopkins billing machine disclosed in said parent application being characterized by a tally roll on the tally strip of which a duplicate record is kept of the items and totals thereof paper carried by the paper carriage located at the upper forward portion of the machine and on the sheet of paper carried by which is also received printing impressions from the words-printing mechanism of the type- Writer.

ln the parent case, there is disclosed an auxiliary paper carriage supportingv the tally strip which may be manually or automatically tabulated to position said strip to Specification of LettersPatent.

receive printing impressions from the tally roll type in different columns. There is also means for returning` the paper carriage of the tally roll mechanism to its home or starting position. This present application relates to the means for feeding the tally strip and controlling the feed thereof so that line-spacing' of the tally strip only occurs *when necessary or desired.

ln the drawings, l indicates the digit key and 2 the result keys thereof. 3 is the motor key for effectin?3 an operation of the adding mechanism. 4 are the keys of the typewriting mechanism. 5 is the laterally movablepaper carriage identified with the typewriting mechanism and on the sheet of paper carried by which are also made impressions from type carried Lvby the type-carriers 100, as set forth in the parent case. 6 is the platen of the laterally] movable carriage before referred to. 119 and 268 are the register Wheels.

500 is the casing or housing which incloses the rear portion of the adding mechanism, said housing or casing having brackets gli extending rearwardly therefrom, in/W'liich brackets is arranged a grooved shaft 502. 503 arc the side frame pieces of the tall),7 roll paper carriage from which is suspended a traine 512 carrying the roll 516 containing the tally strip. This tallyv strip is icd upwardly over an idle roller .5l/l and between pressure rollers 508 and 509, then between suitable paper guides 50S and under platen 505. A serrated plate 50i is secured to the upper cross bar of the frame 503 on the edge of which the tally strip may be severed. lvleansare disclosed in the parent case Yfor tabulating the frame 503 so as to laterally adjust the tally strip opposite the printingtypc on the vsegue-nts 561, such tabulation occurring after said printing segments have been positioned by the racks 100. When positioned, the type are caused to make an impression by vibrating the frame 508, causing the platen 505 to press the paper against the type in the printing` line. 562 indicates the inking ribbon which is normally located over the type in the printing shown in the accompany/ingl d rz rings as be pled-up with the mechanism printing impression of the platen 505, but it is obvious that the paper feed controlling mechanism may be separated therefrom. The laterally movable paper carriage 5 carries a notched bar 89 on which are adjustably mounted blocks 578 supporting pivoted stops 579. These stops coperate with an arrow head 577a on the forward end of a bar 577 having a. slot and pin connection with a frame part of the machine, as shown in Figs. l and 6, whereby when t-he carriage 5 is moved laterally, these stop blocks 57 9 will successively pass the arrow head 577a and, by engaging the anticlinal portions thereof, force the bar 577 rearwardly. f this lateral movement is incident to tabulation. the blocks 579 are so positioned on the ber 39 that at the end of each tabulation movement, they will lie in front of the head 577L and in this mannerhold the bar 577 rearwardly while the paper carriage 5 is stationary.

The rear end of bar 577 is connected to a rock arm 576, on the inner end of sleeve 57a mounted on the shaft 575, finding bearing in the frame parts of the machine. The upper end of sleeve 574 carries an arm 573 to which is connected a bar 572 having a slot and pin connection with the side framing of t-he machine whereby the rear yend of said bar may be guided in its movement. The rear end of bar 572 is bifurcated and normally engages the upper end of a lever 570 carrying the pin 570a at its upper end. This pin is normally held forward by means of springs 570i. The lower end of bar 570 is connected to a moving part of the adding mechanism, not shown herein, but which causes the bar 57() to be operated at each operation ofthe adding mechanism, f1'. e., the bar 570 is first caused to be lowered and then to be raised. If the bar 577 stands in its forward position during this operation of the adding mechanism, the vibration of bar 570 will be idle; but if onel of the stops 579 holds the, bar 577 rearwardly. pin 57W on the upper end of bar 57() will be 4caused to engage in slot 568a in the forward end of leven568 mounted on shaftl 502. and

consequently, said lever 568 will be operated. 5.1%.. rocked.first downwardly, then upwardly. Lever 568 is provided with an adjustable stop 569 on its outer end which wall of the slot. Hence in the normal posiengages track plate 520 and in this way tion of the parts, the guard finger is held below the slot, as shown in Fig. 5, so that pin 570a is free to move into and out of the slot, depending upon the position of the bar 577.

Plate 568 is fixed to the shaft 502 and when the pin 570a lies in the slot, as shown in Fig. 5, the adding mechanism is operated, and bar 570 will be depressed, which movement causes the plate 568 to .be likewise depressed, rocking the shaft 502. As the bar 570 moves downward, its pin 570a will pass behind guard finger 582 and eventually engage the guard plate 581 and cause it to move in unison with plate 568. iVhen pin 570a is thus located behind the guard finger, the guard fin ger closes the slot 5681 and prevents the withdrawal of pin 570% On the upward movement of bar 570, the plate 568 and the guard plate 581 will rise. together until the guard plate is arrested by the shouldered stop C. The continued upward movement of the plate 568 will locate the yslot 568a above the guard finger, as shown in Fig. 5. and the slot being thus exposed, the pin 570"L may be disengaged from the plate 568` which will occur when stop 579 on the paper carriage is movedout of engagement with the arrow head 577A.

Plate 568 carries a post 568b which passes through a slot. in the guard plate 581. This post is fixed to the plate 568 and carries a fixed arm 584 at its outer end, which fixed arm is provided with a pin or lateral projection 585. This pin coiiperates with a bell crank lever 593 mounted on the end of a shaft 5011 (see Fig. 5) which shaft, by its rocking movement, effects the feeding of the inking ribbon not claimed herein).

lhen the plate or rock arm 568 is depressed to rock the shaft 502, the platen carried by the frame 508. is brought into contact with the type in the'prining line, but the. pressure necessary for effecting the printingimpression is not exerted upon said platen until the lost motion between the plate 511 and slot in the shaft 502 is taken up. `When this lost motion has been over come. the final pressure is placed upon the platen. this occurring at the last operation of the downward movement. of thev rock arm 568.

lVhen the rock arm or plateI 568 is lifted` it is imn'laterial whether the frame 503 is first restored to its normal position or whether the lost motion of the plate in the groove is first taken up. The normally retracted position of the frame is determined by means disclosed in the parent application. and when the frame 508 is arrested in its retracted position, the shaft 502 continues to be rocked. thereby absorbing the lost motion referred to until the stop member 56.0 engages the track plate 520. T his continued rocking movement of the sey sha-ft 502- is utilized in line-spacing the tally strip.

@ne end of the paper feed roll 509 (the right-hand end, as viewed from the front of the machine, see Fig. i) is provided with a hand-Wheel 586 for manual operation. The opposite end oi2 said feed roll is provided n'ith'a ratchet Wheel 587, (see also Fig. 7 This ratchet Wheel cooperates with a spring-pressed centering pin 588 carried by an arm pivotally connected 'to the frame 503, Which centering pin permits the manual rot-ation of the feed roller 509 in either direction. A

To mechanically e'ect the line-spacing the paper, l mount a plate 58S (see on the shaft. 502, said plate having snc-t and pin connection, with the iraine 50o, so as to permit independent movement thereof, and said plate also having a proj-ation which fits into the groove oi" shaft 5G52, ont not tightly, permitting a slight independent play o'rl said plate. Plate 589 carries a paper feeding pawlvd@ which is normally held in operative position by a Spring 591. A har K 55,92 Figs. l and is monnted in a bearing provided by one of the brackets 50i, saidhar being adjustahly held in position by means et av set screw This bar is ont away at intervals, as at 592, so that Whenever said har is adjusted to locateone of its cut-away portions opposite, or in line with, the paperfeeding parvl'QO, (see Fig. 7) said paperfeeding pawl is peri itted to engage the ratchet Wheel and line-space the tally strip. l/Vhen, however, the paper-feeding pawl 590 rides upon the har, as shown by dotted lines in "l, the 'vibration of the psw-l 596 will loe idle. Thus, after a printing impression,

and after 'che frame 503. has been retracted.

the full measure of its retractive movement, continued roc 'ing of the shaft 502 in taking npiostniotion tiierehetween said frame, will rock the plate 589 and Vilar-ate the paper-feeding paWl 59m. li the bar 392 is so adjusted as to have. a recess in line with said paperieeding pawl, then the. papereeding pani 4will engage, and hy operating the ratchetwheel, line-space the tally strip; but, if' said papeniieeding pawl is riding the bar, its vibration will he idle.

The har 592 is'sntiicientiy long (see Figs. l and 3) to hold the paper-feeding pawl 590 in a disabled position throughout the entire travel ci the tally-roll carriage, except when it. occupies that position which may he de:- ignated as the extreme left position, when, hy the presence of the recess 5923, line-spacing will he eected. The har 59;?. may have a second recess 5925 ont on its opposite side, as shown in Fig. 3, so that hy rotating the har linespacing ci the tally striJ can be eilected at a point betere the carriage reaches its extreme left. position. @f course,
